无法访问http://localhost:8888/uploads/ url、Spring Boot、Tomcat下的静态文件
我有以下项目文件夹结构
假设我有空的 /resources/static/uploads 文件夹
通过一个网站，在我的 FileService 的帮助下，添加一张图片并将其保存在 /resources/static/uploads 中
@Service
public class FileService {
@Value("${app.upload.imgsdir:${user.home}}")
private String uploadDir;
public String uploadFile(MultipartFile file) {
try {
String FullFileName = UUID.randomUUID().toString() + '.' + file.getOriginalFilename();
Path copyLocation = Paths.get(uploadDir + File.separator + StringUtils.cleanPath(FullFileName));
Files.copy(file.getInputStream(), copyLocation, StandardCopyOption.REPLACE_EXISTING);
return FullFileName;
} catch (IOException e) {
e.printStackTrace();
throw new FileStorageException("Could not store file " + file.getOriginalFilename()
+ ". Please try again!");
}
}
public void delFile(String fileName) {
try {
Files.delete(Paths.get(uploadDir + '/' + fileName));
} catch (IOException e) {
throw new FileStorageException("Could not delete file " + fileName
+ ". Please try again!");
}
}
}
然后如果我尝试使用 url 访问它 http://localhost:8888/uploads/f3dc9351-1c64-4d96-b084-176becc07546.unnamed.jpg 我收到以下错误
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
